Just wondered if anybody has tried some filter media I have seen on youtube, called Biohome Ultimate. Has anybody tried it out, if so what do you think. If not, check out the vids by some guy who goes by the name of Pondguru,
He runs a company called Tyne Valley Aquatics in the UK. And sells the stuff on ebay, be interesting to hear other peoples opinions of it. Looks and sounds like it might be quite good stuff.
